These field guides include keys to the entire flora but lack morphological descriptions. Nonetheless, comments about habitats, abundance, distribution, similarities to closely related taxa, native or alien status, taxonomic notes, synonyms, and various interesting tidbits are included after the species names in the keys. Included are more than pages of line drawings at the end of each field guide.
By dividing the state into 2 sections, the size of each field guide and the length of the keys remain manageable for field use. As the names imply, the western slope guide covers everything west of the continental divide, and the eastern slope guide covers everything east of the divide.
Plants in the Colorado high country are fairly well covered by either field guide. These 2 guides had their beginning in with publication of the Handbook of Plants of the Colorado Front Range. This handbook was followed in by the Rocky Mountain Flora. These guides follow the same format as previous editions, but the nomenclature has been updated.
For example, all Cleome in Colorado are now Peritoma. Synonyms and common names are included in the index so you can still locate a given species in the field guide even if you know only the old name or the common name, but not the new scientific name. Moreover, as techniques and concepts change, cladists arrange and rearrange their molecular phylogenies APG in , APG II in , APG III in , seemingly debating as did the perhaps apocryphal theologians of yore about how many angels can dance on the head of a pin.

Ultimately, if and when a molecular phylogeny is finalized for the angiosperms and the other supergroups, molecularists must provide a reliable nomenclator guide for their new names versus the old field names of the guidebook realists. Hopefully such a concordance will not be a "total nightmare," as already claimed for the name changes in California's phylogenetic second edition of The Jepson Manual ; see separate reviews by R.
Schmid and E. Dean, Taxon —; see also previous review. Although we feel that it is premature to adopt the new taxonomy, lock, stock, and barrel, we often mention at least the proposed changes. In any case, professional and amateur field botanists require a practical classification scheme that is based primarily on morphology and ecology, and that de-emphasizes characters that cannot be easily observed. Practicality thus is the guiding principle.

We feel that the phylogenetic approach does not take into consideration the various kinds of barriers cytological, seasonal, ecological, and morphological that separate the generic divisions" pp. For example, regarding the new cladistic world where the family Scrophulariaceae is now a rump group, at least in the western United States [ Unnatural or not, the traditional Scrophulariaceae remains a useful, morphologically recognizable group, for Colorado at least, and we keep it together in deference to our amateur readers.
For practical reasons, we prefer the traditional treatment. There has always been reaction to taxonomic change, of course. Two famous cases are Sequoia gigantea becoming Sequoiadendron giganteum in and Pseudotsuga taxifolia becoming nomenclaturally P.
Dayton, , The names of the giant sequoia: a discussion, Leafl. Little, Jr. However, such changes have been on a limited scale, unlike the massive realignments demanded by cladistics. Colorado and California both have rich floras, California with roughly twice as many species in a The phylogenetic second edition of The Jepson Manual was developed with an army of contributors, including 6 main editors.

In contrast, the fourth edition of Colorado Flora was essentially a two-man effort. See also the "Considerations" commentary following. I conclude with a few remarks about other aspects: 1 I failed to find in editions 3 and 4 of Colorado Flora an indication of how many taxa are newly added compared to the previous edition.
The paragraph "some floristic statistics" has the same information in editions 2, 3, and 4: the eastern slope has families and about species, only on that slope; the western slope has families and about species, only on that slope pp. Perhaps nonagenarian Weber has better eyesight than septuagenarian Schmid.
